iOS 捕获崩溃

用苹果提供的api NSSetUncaughtExceptionHandler进行捕获

void CustomExceptionHandlers(NSException *exception){

    NSMutableDictionary *userInfo= [NSMutableDictionary dictionaryWithDictionary:[exception userInfo]];

    [userInfo setObject:exception.callStackSymbols forKey:@"CallstackSymbolsKey"];

    [userInfo setObject:[exception name] forKey:@"NameKey"];

    [userInfo setObject:[exception reason] forKey:@"ReasonKey"];

    NSLog(@"%@",userInfo);

    //可以在这个位置进行一些操作，比如保存或上传等，可以将堆栈信息一起上传

}

+(void)uncaughtSignalExceptionHandler {

    NSSetUncaughtExceptionHandler(&CustomExceptionHandlers);

}

uncaughtSignalExceptionHandler 可在项目启动时进行调用
